The Fascinating History of Klis Fortress, Croatia
Perched high above the Dalmatian coast, Klis Fortress has stood watch over Croatia’s heartland for more than two millennia. Its position between the Kozjak and Mosor mountains made it one of the most strategically important strongholds in the region—so much so that it earned the name “The Key to Dalmatia.”
From Illyrian Beginnings to Roman Rule
The story of Klis begins long before Croatia existed as a nation. The first fortifications were built by the Illyrian tribe Dalmatae around the 2nd century BCE. They chose this rocky ridge for its commanding view over the inland valleys and the Adriatic Sea—a perfect vantage point to defend their settlements from rival tribes.
When the Romans conquered Dalmatia in the 1st century BCE, they recognized the fortress’s importance and reinforced it as part of their defensive network. Klis (known then as Clissa) became a key watchpoint protecting the Roman city of Salona, one of the most significant Roman centers on the Adriatic.
Medieval Croatia and the Kingdom’s Stronghold
After the fall of the Western Roman Empire, Croatian tribes settled in the area, and Klis became the seat of Croatian dukes and kings. For centuries, it was one of the main royal residences of early medieval Croatia, with legends claiming that King Tomislav, Croatia’s first king (crowned around 925 AD), once ruled from this very fortress.
During the 11th to 13th centuries, Klis continued to grow in importance as a royal and administrative center. Its stone walls were expanded, towers added, and its defenses improved to guard against external invasions—from both inland and the sea.
The Heroic Defense Against the Ottomans
Klis’s most dramatic chapter came during the 16th century, when the Ottoman Empire expanded into the Balkans. The fortress became a symbol of resistance for the entire region.
The legendary Petar Kružić, a Croatian nobleman and military captain, led a group of fierce defenders known as the Uskoks. For more than two decades, they held off repeated Ottoman assaults against overwhelming odds. Kružić’s defense from 1515 to 1537 is one of Croatia’s proudest historical episodes—an example of courage, faith, and patriotism.
However, after his death in 1537, the fortress finally fell to the Ottomans. The capture of Klis marked the end of Croatian control over much of Dalmatia’s interior for more than a century.
Venetian and Habsburg Eras
In 1648, during the Cretan War between Venice and the Ottoman Empire, Venetian forces recaptured Klis Fortress. They immediately strengthened its walls, added artillery bastions, and integrated it into their coastal defense system.
After the fall of Venice in the late 18th century, Klis came under French control during the Napoleonic Wars, then passed to the Austro-Hungarian Empire, which maintained it as a military post.
Each empire left behind traces—battlements, gates, chapels, and architectural styles—that make Klis a living museum of Mediterranean military history.
Klis in Modern Times
By the 19th century, the fortress lost its military role and fell into disrepair. But in recent decades, it has been lovingly restored by local historians and the Municipality of Klis, transforming it into one of Croatia’s most atmospheric historic landmarks.
Today, Klis Fortress draws visitors from around the world—not only for its panoramic views over Split and the Adriatic islands, but also as a filming location for Game of Thrones. In the series, Klis appeared as the city of Meereen, bringing a new generation of travelers to this ancient Croatian treasure.
Why Klis Fortress Matters
Klis is more than just an old fortress—it’s a symbol of endurance. For centuries, it has guarded the path between the Dalmatian coast and the Croatian interior. Each layer of its stone tells a different story: Illyrian beginnings, Roman precision, medieval pride, Ottoman conquest, Venetian resurgence, and modern rebirth.
To visit Klis Fortress today is to step through every chapter of Dalmatia’s past—an experience that blends history, culture, and breathtaking scenery in one unforgettable stop.

Klis Fortress and Game of Thrones: The Real-Life City of Meereen
If you’re a Game of Thrones fan, Klis Fortress in Klis, Croatia, will feel instantly familiar. High above the Dalmatian coast, this ancient stronghold became one of the most recognizable filming locations in the series — the City of Meereen, the great Slaver City conquered by Daenerys Targaryen.
Filming the City of Meereen
In Season 4 of Game of Thrones, production teams transformed Klis Fortress into the dramatic mountaintop city of Meereen. The fortress’s rugged stone walls, narrow stairways, and panoramic views over Split and the Adriatic Sea provided the perfect real-world setting for the fictional city.
It was here that Daenerys Targaryen, the “Mother of Dragons,” marched her army up the winding path to confront the slave masters of Meereen. Fans will recognize the fortress gates and terraces from several key scenes, including the powerful moment when the people of Meereen rise up and remove the chains that once bound them.
The show’s producers, who scouted dozens of locations across Croatia, ultimately chose Klis because of its authentic medieval architecture and breathtaking vistas. Its fortress-like silhouette, carved into the cliffs, made CGI almost unnecessary — much of what you see on screen is the real Klis.
How Klis Transformed for Filming
To recreate Meereen, HBO’s production crew made subtle modifications to the fortress and its surroundings. CGI towers and domes were later added digitally to give it the signature Meereen skyline, but most of the ground-level shots — the archways, courtyards, and walls — are exactly as they appear today.
Local craftsmen and extras were hired for the filming, bringing excitement to the small town of Klis. Residents still remember the days when the fortress bustled with camera crews, actors, and even dragons (well, digital ones!).
Visiting Klis Fortress as a Game of Thrones Fan
Visiting Klis Fortress today is like stepping straight into the world of Game of Thrones. You can walk the same stone paths where Daenerys stood, explore the terraces where she addressed the freed slaves, and gaze out over the same sweeping views that framed the show’s epic scenes.
There’s even a small Game of Thrones exhibition inside the fortress, featuring behind-the-scenes photos, props, and information about the filming process. Some guided tours in Split include a Game of Thrones filming locations tour that stops at Klis Fortress, Diocletian’s Palace, and Kaštel Gomilica, offering a full day of exploring the show’s real-world backdrops.
